Description

[0001] Cross-references to related applications

[0002] This application claims priority and interest in U.S. Provisional Application No. 63 / 795,939, filed April 28, 2025, pursuant to 35 USC §119(e), which is incorporated herein by reference in its entirety. Technical Field

[0003] This disclosure generally relates to the field of cooling systems, and more specifically to humidifier access mechanisms for cooling systems. Background Technology

[0004] Recent regulations have been adopted to phase out the production and consumption of hydrofluorocarbons (HFCs), which have high global warming potential (GWP) and exacerbate climate change. Many refrigerants used in cooling systems contain HFCs and therefore have high GWPs. Consequently, new refrigerants compliant with recent regulations have been adopted. For example, R-454B is a newer refrigerant that will gradually replace R-410A. R-454B has a lower GWP than previous refrigerants; however, it is classified as a flammable A2L refrigerant.

[0005] Due to its flammability, this refrigerant has caused problems for current infrared humidifiers used in existing cooling systems, leading to a reversal to steam humidifiers. Steam humidifiers are typically larger than infrared humidifiers, and such a transition is difficult due to existing space constraints in cooling systems.

[0006] In addition, the conversion to electronically commutated (EC) fans within the fan section of the cooling system reduces the amount of available space in the cooling system and imposes significant space constraints on the steam humidifier.

[0007] Therefore, there is a need for systems and methods that address one or more shortcomings of existing approaches. Summary of the Invention

[0009] According to one or more embodiments of this disclosure, a humidifier access system is disclosed. In one embodiment, the humidifier access system includes: an actuation mechanism configured to move a humidifier cabinet housing a humidifier between a maintenance position and an operating position, wherein the actuation mechanism includes: a stationary portion coupled to one of the frames within the humidifier cabinet or the evaporator fan section; and a movable portion coupled to one of the frames within the humidifier cabinet or the evaporator fan section, wherein when in the maintenance position, the humidifier remains in operation, and wherein the humidifier is coupled to one or more hoses.

[0026] The details of the disclosure will now be referred to in detail in the accompanying drawings.

[0027] Recent regulations have been adopted to phase out the production and consumption of hydrofluorocarbons (HFCs), which have high global warming potential (GWP) and exacerbate climate change. Many refrigerants used in cooling systems contain HFCs and therefore have high GWPs. Consequently, new refrigerants compliant with recent regulations have been adopted. For example, R-454B is a newer refrigerant that will gradually replace R-410A. R-454B has a lower GWP than previous refrigerants; however, it is classified as a flammable A2L refrigerant. Due to its flammability, such a refrigerant has caused problems for infrared humidifiers used in many existing cooling systems, leading to a resurgence towards steam humidifiers. Steam humidifiers heat water to produce steam and are typically larger than infrared humidifiers that use heated lamps, making such a transition difficult due to existing space constraints in cooling systems.

[0028] Additionally, within the fan section of the cooling system, there is a shift towards electronically commutated (EC) fans. EC fans are inherently more efficient than conventional centrifugal fans due to their unique design using a brushless electronically commutated motor in a backward-curved motorized impeller. This design requires the space immediately above and below the fan to remain open, resulting in significant space constraints for the steam humidifier.

[0029] Embodiments of this disclosure relate to a humidifier access mechanism. The humidifier access mechanism can allow a humidifier (e.g., a steam humidifier) ​​to be in either a maintenance position (e.g., an extended position) or an operating position (e.g., a retracted position). For example, the humidifier can be rotated and / or translated to the maintenance position via the humidifier access mechanism. In this regard, when in the maintenance position, the humidifier's electrical box (or control panel) can be accessed. When in the maintenance position, the humidifier can be in operation such that rotation and / or translation of the humidifier via the humidifier access mechanism does not impede the operation of the humidifier. For example, the humidifier's hose can remain connected when in the maintenance position, minimizing the risk of equipment damage due to fluid leakage from the hose.

[0030] Figures 1A to 1C A cooling system 100 (or computer room air conditioning (CRAC) system) according to one or more embodiments of the present disclosure is depicted.

[0031] Cooling system 100 may include indoor units 101 (e.g., CRAC units) installed in a data center or computer room, and outdoor units, wherein the outdoor units include an external condenser 103 mounted externally (e.g., on a roof or mezzanine structure) and coupled to the indoor units 101 (e.g., CRAC units). Cooling system 100 may include any type of cooling technology, such as, but not limited to, direct expansion (DX) cooling systems. Furthermore, it is contemplated herein that cooling system 100 can be designed for any suitable configuration, such as, but not limited to, downflow, upflow, or frontal flow configurations.

[0032] The indoor unit 101 of the cooling system 100 may include, but is not limited to, one or more evaporator coils 102 (or cooling coils), one or more fans 104, one or more compressors 106 and one or more humidifiers 108.

[0033] One or more evaporator coils 102 may be configured to supply a cooled liquid (e.g., refrigerant) to the cooling system 100 to absorb heat within a data center or computer room. Additionally, one or more evaporator coils 102 may transfer heat from a return fluid (e.g., return refrigerant) from the cooling system 100 to a cooler medium, such as ambient air, via an external condenser unit. In some cases, one or more evaporator coils 102 may include one or more “V-coil” assemblies (or “V-condenser blocks”) comprising one or more “V-shaped” coils. In other cases, one or more evaporator coils 102 may include one or more flat coil assemblies comprising one or more flat coils. It is contemplated herein that the evaporator may include any type of evaporator coil, and therefore the above description and associated drawings should not be construed as limiting the scope of this disclosure.

[0034] The refrigerant may include a phase change refrigerant. It is contemplated herein that a phase change refrigerant may include any suitable refrigerant, such as, but not limited to, R-454B, R-410A, R-401C, R-32, etc. In some cases, the refrigerant may be a low-GWP refrigerant that meets industry standards and / or regulations (e.g., EU F-Gas Regulation 2024 / 573), wherein the refrigerant used in system 100 may have a GWP of less than 750.

[0035] One or more fans 104 may be arranged in the evaporator fan section 105 of the cooling system 100. For example, one or more fans 104 may be arranged close to one or more evaporator coils 102.

[0036] One or more fans 104 may include one or more electronically commutated (EC) fans 104. As discussed earlier herein, the space immediately above and below one or more EC fans 104 must remain open. For example, one or more EC fans 104 may include a brushless electronically commutated motor in a backward-curved motorized impeller. In this respect, one or more EC fans 104 are inherently more efficient than conventional centrifugal fans; however, one or more EC fans 104 create significant space constraints in the evaporator fan section 105 of the cooling system 100.

[0037] One or more compressors 106 may be configured to circulate refrigerant through an external condenser 103 located on the outside. It is contemplated herein that one or more compressors 106 may be compressors of suitable types, including but not limited to scroll compressors, centrifugal compressors, rotary compressors, etc.

[0038] One or more humidifiers 108 may be arranged in the evaporator fan section 105 of the cooling system 100. For example, one or more humidifiers 108 may be arranged close to one or more EC fans 104.

[0039] One or more humidifiers 108 can be configured to control the humidity level within an indoor unit of the cooling system 100. For example, one or more humidifiers 108 can be activated when the relative humidity in the data center (or computer room) drops below a humidity setpoint (or threshold). In this respect, one or more humidifiers 108, when activated, can increase the amount of moisture in the data center (or computer room).

[0040] In an implementation, one or more humidifiers 108 may include one or more steam humidifiers. For example, one or more steam humidifiers 108 may be configured to heat water to generate steam, thereby increasing the amount of moisture in a data center (or computer room).

[0041] For the purposes of this disclosure, unless otherwise stated herein, "steam humidifier" can refer to a humidifier that heats water to produce steam, thereby increasing the moisture content of an environment. System 100 is intended to include any type of steam humidifier, including but not limited to electrode humidifiers, resistive humidifiers, gas humidifiers, etc.

[0042] One or more humidifiers 108 may be housed within a cabinet 110 (or enclosure) that defines a cavity for holding the steam humidifiers 108. The humidifier cabinet 110 may also include a door (or other access mechanism) to provide access to the cavity holding the steam humidifiers 108. The humidifier cabinet 110 may be coupled to an electrical box 112 configured to control one or more parameters of the steam humidifiers 108.

[0043] As discussed earlier in this document, the infrared humidifier previously used in the cooling system posed a flammable risk due to the refrigerant change. The steam humidifier 108 is typically larger than the infrared humidifier, thus creating space constraints in the evaporator fan section 105 of the cooling system 100. Consequently, access to the steam humidifier 108, electrical box 112, or other humidifier-related components is difficult during maintenance. The humidifier access system 200 is intended to prevent the need for redesign of the evaporator fan section 105 and to allow for the retrofitting of existing systems using steam humidifiers.

[0044] Figures 2A to 5B A humidifier access system 200 for a cooling system 100 is depicted according to one or more embodiments of the present disclosure.

[0045] The humidifier access system 200 can be coupled to the cabinet 110 of the humidifier 108. For example, the humidifier access system 200 can be coupled to the top of the humidifier cabinet 110. The humidifier access system 200 can also be coupled to a portion of the evaporator fan section 105 of the cooling system 100. For example, the humidifier access system 200 can be mounted on the frame of the cooling system 100.

[0046] In one embodiment, the humidifier access system 200 includes an actuation mechanism configured to move the humidifier cabinet 110 of the steam humidifier 108 between a maintenance position (e.g., an open or extended position) or an operating position (e.g., a closed or retracted position). For example, the actuation mechanism may be configured to rotate or translate (e.g., slide) the humidifier cabinet 110 of the steam humidifier 108 between at least one of the maintenance position (e.g., an open or extended position) or the operating position (e.g., a closed or retracted position). In this respect, when in the maintenance position, one or more components of the humidifier (e.g., humidifier 108, electrical box 112, humidifier duct / hose, etc.) can be accessed, allowing maintenance to be performed. Furthermore, when in the maintenance position, the humidifier 108 can be in operation, such that rotation and / or translation of the humidifier 108 via the humidifier access system 200 does not impede the operation of the humidifier 108. For example, one or more hoses of humidifier 108 may remain connected to the humidifier during rotation and / or translation, thereby minimizing the risk of equipment damage due to fluid leakage from the hoses.

[0047] For the purposes of this disclosure, "operating position," "collapsed position," or "off position" may refer to the position of the humidifier cabinet 110 in which the humidifier 108 is configured to operate normally within the evaporator fan section 105 of the cooling system 100. When in the operating position, the humidifier cabinet 110 may be fixed to the frame of the cooling system 100 and positioned such that the humidifier 108 provides humidity control to a data center or computer room.

[0048] For the purposes of this disclosure, "maintenance position," "expanded position," or "open position" may refer to the following positions of the humidifier cabinet 110 where one or more components of the humidifier 108 are accessible for servicing, inspection, or repair. When in the maintenance position, the humidifier cabinet 110 may be translated and / or rotated relative to the operating position to provide clearance for technicians to access the humidifier 108, electrical box 112, humidifier piping, or other humidifier-related components.

[0049] One or more hoses coupled to the humidifier 108 may include, but are not limited to, water supply hoses, drain hoses, and / or steam output hoses. One or more hoses may be configured to have sufficient length and flexibility to accommodate translational or rotational movement of the humidifier cabinet 110 between its operating and maintenance positions. For example, one or more hoses may comprise flexible tubing (e.g., reinforced rubber hoses, braided stainless steel hoses, etc.) of sufficient length to allow the humidifier cabinet 110 to translate or rotate through its entire range of motion without disconnection. In this regard, one or more hoses may be routed within the evaporator fan section 105 to provide a slack section when the humidifier cabinet 110 is in the operating position, such that the slack section is tightened when the humidifier cabinet 110 is moved to the maintenance position. The routing of one or more hoses may be configured to avoid interference with one or more EC fans 104 and other components within the evaporator fan section 105.

[0050] The electrical box 112 can be positioned on the front or side of the humidifier cabinet 110. For example, due to space constraints within the evaporator fan section 105, the electrical box 112 can be positioned such that access to the electrical box 112 is blocked when the humidifier cabinet 110 is in the operating position. In this regard, the humidifier access system 200 can be configured to move the humidifier cabinet 110 to a maintenance position, thereby providing clearance for technicians to access the electrical box 112. The electrical box 112 may include one or more electrical connections (e.g., power connections, control signal connections, sensor connections, etc.) that are accessible when the humidifier cabinet 110 is in the maintenance position. Similar to one or more flexible hoses, one or more electrical connections can be configured to have sufficient length and flexibility to accommodate translational or rotational movements of the humidifier cabinet 110 between the operating and maintenance positions.

[0051] This document anticipates that the humidifier cabinet 110 can be positioned in one or more intermediate positions as it moves between a maintenance position and an operating position (and vice versa). For the purposes of this disclosure, an "intermediate position" may refer to the position of the humidifier cabinet 110 between an operating position and a maintenance position. When in an intermediate position, the humidifier cabinet 110 may be partially translated and / or partially rotated relative to the operating position, such that the humidifier cabinet 110 is neither fully fixed in the operating position nor fully extended into the maintenance position.

[0052] Overall reference Figures 2A to 3DThe actuation mechanism of the humidifier access system 200 includes a translation (or sliding) mechanism 202. The translation mechanism 202 may include a stationary portion 204 and a translation (or sliding) portion 206 (or a movable portion 206). For example, the stationary portion 204 may be coupled to the frame of the cooling system 100, and the translation (or sliding) portion 206 may be coupled to the top of the humidifier cabinet 110. As another example, the stationary portion 204 may be coupled to the top of the humidifier cabinet 110, and the translation (or sliding) portion 206 may be coupled to the frame of the cooling system 100.

[0053] Reference Figure 2C In a non-limiting example, the stationary portion 204 may include, but is not limited to, a top surface 204a, one or more side surfaces 204b (or sidewalls), one or more bottom surfaces 204c, and one or more rear surfaces 204d. The top surface 204a, one or more side surfaces 204b, one or more bottom surfaces 204c, and one or more rear surfaces 204d of the stationary portion 204 may be formed of metal (e.g., a metal sheet). In this regard, the metal sheet of the stationary portion 204 may be bent to form at least one of the one or more side surfaces 204b, one or more bottom surfaces 204c, and one or more rear surfaces 204d. Furthermore, one or more holes (and / or cutouts) may be punched through the metal sheet of the respective surfaces of the stationary portion 204.

[0054] Reference Figure 2D In a non-limiting example, the translation (or sliding) portion 206 may include, but is not limited to, a bottom surface 206a, one or more sides 206b (or sidewalls), one or more front surfaces 206c, and one or more rear surfaces 206d. The bottom surface 206a, one or more sides 206b, one or more front surfaces 206c, and one or more rear surfaces 206d of the translation portion 206 may be formed of metal (e.g., a metal sheet). In this regard, the metal sheet of the translation portion 206 may be bent to form at least one of the sides 206b, one or more front surfaces 206c, and one or more rear surfaces 206d. Furthermore, one or more holes (and / or cutouts) may be punched through the metal sheet of the respective surfaces of the translation portion 206.

[0055] The stationary portion 204 and / or the translational portion 206 are intended to be formed of any suitable material, such as, but not limited to, stainless steel, galvanized steel, aluminum, etc.

[0056] The translation mechanism 202 may also include one or more slots 208. Each slot 208 may include a first portion 210 and a second portion 212. For example, the first portion 210 may be a vertical, substantially flat portion and is configured to couple to the stationary portion 204. For example, as Figure 2A , Figure 2C , Figures 3A to 3C As shown, the first portion 210 can be configured to couple to the front end of the stationary portion 204, wherein the first portion 210 is parallel to one or more sides 204b of the stationary portion 204. Furthermore, the second portion 212 may include at least partially defining a vertically substantially flat portion and a horizontally substantially flat portion of the cavity 214. For example, as... Figure 2A , Figure 2D , Figures 3A to 3C As shown, the vertical, substantially flat portion of the second part 212 may be parallel to one or more sides 206b of the translation (or sliding) part 206, and the horizontal, substantially flat portion of the second part 212 may be perpendicular to one or more sides 206b of the translation (or sliding) part 206.

[0057] The translation mechanism 202 may include a linear guide 216 configured to translate along a vertical axis within the cavity 214 of the slot 208. For example, the translation (or sliding) portion 206 may include (or be coupled to) the guide 216. In one example, such as Figures 2A to 2D As shown, one or more sides 206b of the translation portion 206 can be used as linear guides 216. In this respect, as Figure 3B As shown, one or more sides 206b of the translation portion 206 can be translated along a vertical axis (e.g., the y-axis) within the cavity 214 of the slot 208 from an operating position (e.g., a retracted position) to a maintenance position (e.g., an extended position), making the humidifier cabinet 110 accessible. In another example, although not shown, the translation portion 206 (e.g., one or more sides 206b, etc.) can be configured to be coupled to a linear guide rail.

[0058] The translation distance of the translation mechanism 202 can be configured to provide sufficient clearance for maintenance access to the humidifier 108 and the electrical box 112. For example, the length of the slot 208 can limit the maximum translation distance of the humidifier cabinet 110. In a non-limiting example, the translation distance can range from about 4 inches to about 12 inches, although other translation distances are contemplated. The translation distance can be selected based on the dimensions of the humidifier cabinet 110, the location of the electrical box 112, and space constraints within the evaporator fan section 105. In this respect, the translation distance can be sufficient to provide technicians with access to the electrical box 112 and other critical components of the humidifier 108 without requiring the complete removal of the humidifier 108 from the cooling system 100.

[0059] The translation mechanism 202 may include a stop member 218. For example, such as Figure 2A , Figure 2D , Figure 3BAs shown, one or more rear ends 206d of the translation portion 206 can serve as stop members 218. For example, when the guide rail 216 (e.g., one or more sides 206b of the translation portion 206) is in the fully extended position (as shown) Figure 3B When the guide rail 216 is translated (as shown), the groove 208 can lock itself onto the stop member 218 (e.g., one or more rear portions 206d of the translation portion 206) to prevent further translation of the guide rail 216. In this respect, the stop member 218 can prevent the guide rail 216 from disengaging from the groove 208.

[0060] The stop member 218 can be configured to abut against the slot 208 to prevent the guide rail 216 from disengaging from the slot 208 when the humidifier cabinet 110 is in the fully extended maintenance position. For example, the stop member 218 (e.g., one or more rear portions 206d of the translational portion 206) can have a width greater than the width of the cavity 214 of the slot 208, such that the stop member 218 cannot pass through the cavity 214. In this respect, when the guide rail 216 is translated to the fully extended position, the stop member 218 can contact the edge of the slot 208 to prevent further translation.

[0061] The translation mechanism 202 may also include one or more fixing features configured to hold the humidifier cabinet 110 in an operating position during normal operation of the cooling system 100. For example, one or more fixing features may include one or more fasteners (e.g., bolts, screws, finger screws, etc.) configured to secure the translation portion 206 to the stationary portion 204 when the humidifier cabinet 110 is in the operating position. In this regard, one or more fasteners can be loosened or removed to allow the humidifier cabinet 110 to be translated to a maintenance position. In some embodiments, the translation mechanism 202 may include a snap-fit ​​or latching mechanism configured to releasably hold the humidifier cabinet 110 in the operating position without requiring a tool for release.

[0062] The stationary portion 204 and the sliding portion 206 of the translation mechanism 202 can be configured to support the weight of the humidifier cabinet 110 and the humidifier 108 housed therein. For example, the metal plate forming the stationary portion 204 and the sliding portion 206 can have a thickness sufficient to support the combined weight of the humidifier cabinet 110 and the humidifier 108 without deformation. The slot 208 and guide rail 216 assembly can be configured such that the weight of the humidifier cabinet 110 is distributed across the mating surface between the guide rail 216 and the cavity 214 of the slot 208. In this respect, the dimensions of the mating surface can be set to prevent jamming or excessive wear during the translation of the humidifier cabinet 110.

[0063] although Figures 2A to 2D and Figures 3A to 3DThe translation mechanism 202, comprising guide rails and slot assemblies, is depicted herein; however, it is contemplated that translation mechanism 202 may include any suitable translation mechanism, such as, but not limited to, linear guide rails and carriage assemblies (e.g., ball bearing carriages, roller bearing carriages, etc.), slot and recess assemblies, drawer sliding mechanisms, telescopic guide rail assemblies, etc. The selection of the translation mechanism may be based on factors including the weight of the humidifier cabinet 110, the required translation distance, environmental conditions within the evaporator fan section 105, and the ease of operation desired by maintenance personnel. In this regard, translation mechanism 202 may be configured to provide smooth and controlled movement of the humidifier cabinet 110 while supporting the weight of the humidifier 108 and associated components throughout the translation range.

[0064] Overall reference Figure 4 and Figures 5A to 5B The actuation mechanism of the humidifier access system 200 includes a rotating mechanism 400. The rotating mechanism 400 may include a stationary portion 402 and a rotating portion 404 (or a movable portion 404). For example, as... Figures 5A to 5B As shown, the stationary portion 402 can be coupled to the frame of the cooling system 100, and the rotating portion 404 can be coupled to the top of the humidifier cabinet 110. As another example, the rotating portion 404 can be coupled to the frame of the cooling system 100, and the stationary portion 402 can be coupled to the top of the humidifier cabinet 110.

[0065] In a non-limiting example, the stationary portion 402 and the rotating portion 404 may include one or more surfaces (e.g., top surface, bottom surface, side surface, front surface, rear surface, etc.) and are formed of metal (e.g., a metal sheet). In this respect, one or more surfaces may be formed by bending the metal sheet of one of the stationary or rotating portions 404.

[0066] The stationary portion 402 and / or the rotating portion 404 are intended to be formed of any suitable material, such as, but not limited to, stainless steel, galvanized steel, aluminum, etc.

[0067] The stationary portion 402 may include a rotating slot 406. For example, the rotating slot 406 may be a cutout in the bottom surface of the stationary portion 402. It is contemplated herein that the shape and / or size / length of the rotating slot 406 may be adjusted based on the desired amount of clearance space required to rotate the cabinet 110 and provide the desired access.

[0068] Although translation mechanism 202 and rotation mechanism 400 are described separately herein, it is contemplated that humidifier access system 200 may include translation mechanism 202 and rotation mechanism 400 in combination. For example, humidifier access system 200 may be configured to first translate humidifier cabinet 110 and then rotate humidifier cabinet 110 to provide enhanced access to humidifier 108 and electrical box 112. In this respect, the combination of translation and rotation can provide greater flexibility in accessing different components of humidifier 108, depending on the specific maintenance task to be performed, wherein translation can provide vertical clearance for accessing components on the top or bottom of humidifier cabinet 110, while rotation can provide angular clearance for accessing components on the front or sides of humidifier cabinet 110, such as internal components of humidifier 108, electrical box 112, humidifier ducts, or control interfaces that may be obstructed by adjacent structures within evaporator fan section 105 when humidifier cabinet 110 is in the operating position.

[0069] The rotation angle of the rotating mechanism 400 can be configured to provide sufficient clearance for maintenance access to the humidifier 108 and the electrical box 112. For example, the arc length and curvature of the rotating slot 406 can define the maximum rotation angle of the humidifier cabinet 110. In a non-limiting example, the rotation angle can range from about 30 degrees to about 90 degrees, although other rotation angles are contemplated. The rotation angle can be selected based on the dimensions of the humidifier cabinet 110, the location of the electrical box 112, and space constraints within the evaporator fan section 105. In this respect, as the humidifier cabinet 110 rotates about a pivot point defined by the connection between the rotating portion 404 and the humidifier cabinet 110, the rotating slot 406 can bend to follow an arc corresponding to the rotation path of one or more rotating fasteners 408.

[0070] When the humidifier cabinet 110 is in the operating position, one or more rotating fasteners 408 can be fully tightened to secure the rotating portion 404 to the stationary portion 402. In this respect, one or more rotating fasteners 408 prevent accidental rotation of the humidifier cabinet 110 during normal operation of the cooling system 100. One or more rotating fasteners 408 can be configured to be loosened by hand or with standard tools (e.g., wrenches, screwdrivers, etc.) to allow the humidifier cabinet 110 to rotate to a maintenance position.

[0071] The rotating portion 404 may include one or more rotating fasteners 408. For example, one or more rotating fasteners 408 may be arranged on the top surface of the rotating portion 404. The one or more rotating fasteners 408 may include any suitable fasteners, such as, but not limited to, one or more bolts, one or more screws, etc.

[0072] One or more rotating fasteners 408 can be configured to rotate within a rotating groove 406 of the stationary portion 402. For example, one or more rotating fasteners 408 can be at least partially loosened (e.g., loosened) to allow one or more rotating fasteners 408 to rotate along the rotating groove 406 until they are in the desired position. For example, as Figure 5B As shown, the humidifier cabinet 110 can be rotated outward from an operating position (e.g., a retracted position) to a maintenance position (e.g., an extended position). In this regard, the humidifier cabinet 110 becomes accessible, allowing for the maintenance of one of the following: the humidifier, the electrical box 112, the humidifier piping / housing, etc.

[0073] although Figure 4 and Figures 5A to 5B A rotating mechanism 400 comprising a bolt and a groove rotating assembly is depicted herein; however, it is contemplated herein that the rotating mechanism 400 may include any suitable rotating mechanism, such as, but not limited to, a groove and recess rotating assembly. Furthermore, although... Figure 4 and Figures 5A to 5B A rotation mechanism 400 is depicted that causes the humidifier cabinet 110 to rotate along the x-axis, but it is contemplated herein that the rotation mechanism 400 can be configured to rotate along the z-axis, causing the humidifier cabinet 110 to rotate upward.
